LGSLSSL Specification of Letters Patent.

Application filed GctoberB, 1911. Serial No. 652,654.

T all whom it may concern Be it known that I, FRANK N. Bacon, a citlzenof the United States, and a resident of Omaha, in the county of Douglasand haust gases for vulcanizing patches on the tire tubes.

Other objects of my invention are to pro vide means for indicating andfor regulating the temperature of the vulcanizer plate.

Constructions embodying my invention are illustrated in he accompanyingdrawings, in which- Figure 1 is a side view of the chassis of a motorvehicle having my vulcanizer applied 7 to the engine thereof, Fig. 2 isan end view of the vulcanizer, and Fig. 3 is a longitudinal sectionalview thereof. i

In the illustrated embodiment of my invention I provide a hollowrectangular-metallic plate 1, in the lower side of which at the centeris a threaded opening in which is screwed a nipple The other end of thenipple is screwed into a hole tapped in the side. of the exhaust-pipe 3of an internal combustion engine 4, thelatter being shown in Fig. 1 asbeing carried by and forming part of a motor vehicle. Near the edges ofthe bottom of the plate 1 stop-cocks 5 are screwed therein, as shown.

At one side of the plate 1 is a projecting lug through which is avertical opening. A rod passes slidably through said opening and isadjustably held therein by means of a set screw 7. The upper portion of,the rod is bent laterally over the top of the plate.

1 and the end 8 thereof is flattened and has a vertical threaded opening2" which is screwed the threaded stem. :3. The said stem has at theupper end a hand rheel 1G and the lower end a ball 11 which fits into asocket 12 on the top of the swivel-plate 13.

On the side of the plate 1, adjacent to the lug through which the rod 6passes, is a sec: ond lug which has an opening made therein to receivethe thermometer 1 1.

In the operation of the vulcanizer the stop-cocks 5 are opened more orless so that a portion of the exhaust gases from the pipe 3 will pass upthrough the plate 1 and heat the same. After a short time thetemperature of the plate will be'indicated by the thermometer 14f. andif not as desired the temperature may be varied by varying the openingof the cocks 5 so as to permit a greater: or less amount of the exhaustgases to pass through the hollow plate. I have found that the exhaustgases, taken in this way from the exhaust pipe of an ordinary internalcombustion engine such as is used on motor vehicles, will heat the plateuniformly so that any vulcanizable article clamped on the top of theplate between the same and the swivelplate 13 may be quickly andthoroughly vulcanized. I have alsofound that the temperatures are souniform that after the cooks 5 are once regulated they need not bechanged unless there should be an extreme variation of atmospherictemperature which would materially change the rate of radiation from theplate.

The convenience of having the vulcanizer carried directly upon a motorvehicle will be obvious. The device having once been regulated, it isalways ready for immediate use whenever the vehicle is in use or itsengine running. Tire repairs may thus be made at any time or place, itbeing merely necessary to clamp the tube and patch upon the plate 1,leave it in place fora suitable time, say twelve or fifteen minutes, andthe repairing of the tube-is completed.

N ow, having described my invention,what I claim and desire to secure byLetters Patent is:

1. In a vulca'nizing device, a hollow metal plate, means for connectingthe same with the exhaust pipe of an internal combustion engine forsupplying exhaust gases thereto, means for controlling the flow of gasesthrough the plate, and means for holding vulcanizing articles on theplate.

2. The combination with an internal coinbustion engine, of a hollowplate, means connecting the same with the exhaust pipe of the engine,means for controlling the flow of exhaust gases through the plate, andmeans for indicating the temperature of the plate.

3. In a vulcanizing device, a relatively flat Patented July 9, 1912.-

89 111 6 of heated gases under pressure there heated gases, cockscontrolling sald openhollow metal plate, a pipe connected with l bemandarranged to clam 7 p articles against i116 WQIZ side thereof andextending to a the upper side of the plate. In test-in'xony whereof Ihave hereunto e ng openings in the same side of the plate subscribed myname in the presence of two for permitting the escape therefrom of saidWitnesses.
